Architectural Designs and Synthetic Strategies of Advanced Nanocatalysts

Abstract

Advanced nanocatalysts with high compositional and structural tailorability have emerged as a new class of heterogeneous catalysts exhibiting many new technical merits over their conventional counterparts. Generally, preparation of such catalysts involves the integration of catalyst components with compositional, size, and shape controls into a larger material system in order to bring along collective and synergetic effects of individual components. Herein, a brief review of architectural designs and synthetic strategies for making these nanocatalysts is presented. Due to length constraints, only four major types of them are highlighted together with some general rules of design and synthesis. Finally, a critical outline of future perspective in this field is proposed.

Boosting oxygen evolution of single-atomic ruthenium through electronic coupling with cobalt-iron layered double hydroxides

“…In addition, this Ru/CoFe-LDHs interactions can be regarded as the synergistic effect between the active Ru catalytic site and the CoFe-LDHs support. The support effect has been observed in many reports for thermal catalysts 60–63 , and is believed to be helpful for catalyts to achieve remarkable activity, stability, and selectivity 64,65 . It is noteworthy that the Ru local structure does reconstruture when the electrode potential goes back to OCV (Supplementary Fig.…”

Low‐Dimensional Metal‐Organic Frameworks and their Diverse Functional Roles in Catalysis

“…The integration of catalytic NPs to support systems possesses numerous benefits, such as enhanced stability and synergistic effects, which have also been observed with MOFs as the support materials . However, in order to fully exploit the advantages of the composite systems, dimensional control over MOF structures is crucial as well.…”

“…These nanocatalysts have remarkably promoted the chemical production, energy conversion, and environmental remediation . However, the high surface energy of the nanocatalysts which generally result to the irreversible reunite of the catalytic activity sites during the catalytic reactions procedure and finally obtain a bad respond from the catalytic system, namely, the dramatic loss of the catalysts’ original catalytic activity . A plenty of endeavors have been conducted to fabricate stable and efficient nanocatalysts by regulating the structures.…”

“…[23][24][25] However, the high surface energy of the nanocatalysts which generally result to the irreversible reunite of the catalytic activity sites during the catalytic reactions procedure and finally obtain a bad respond from the catalytic system, namely, the dramatic loss of the catalysts' original catalytic activity. [26][27][28][29] A plenty of endeavors have been conducted to fabricate stable and efficient nanocatalysts by regulating the structures. With the careful design and synthesis, the nanomaterials could possess many outstanding properties, such as considerable specific surface areas, chiseled active sites and controllable mass transfer rates, which were all contributions to improve the catalysts' catalytic activity.…”
